CARBURETOR.

SPECIFICATION forming part of Letters Patent N0. 3541574, dated December2l, 1886.

Application filed August 3, 1886. Serial No. 209,885. (No model.) l

To all whmn it may concern,.-

Beit known that I, WILLIAM H. O CONNOR, a citizen of the United States,residing at Day ton, in the county of Montgomery and State of Ohio,haveinvented a new and useful Improvement in Carburetors, of which thefollowing is a specification.

Myinvention relates toimprovementsin car buretors; and it consists inthe details of construction and arrangement of parts, as hereinafter setforth.

In the accompanying drawings, Figure .l is a partly Vertical and partlysectional view of a carburetorembodying my invention. Fig. 2 is ahorizontal sectional view. Fig. 3 is aplan View of the seal to openings`in inner tank. Fig. 4 is a partly vertical and partly sectional viewshowing the purifying-chamber and seal to the openings in the innertank. Fig. 5 is a sectional view showingpartitions and sub-partitionsdividing inner tank into vertical cham bers. Fig. 6 represents aperspective View of the lock embraced in my invention.

Similar letters refer to similarparts in the drawings.

A and B represent, respectively, outer and inner tanks, between which isplaced a lining, C, of asbestus or other suitable nonconductingmaterial. The inner tank, B, is divided into a number of compartments,E, by means of vertical partitions D,which are secured at one end to atubular support, D', and at the other end to the inner wall of said tankB. The support D may be omitted and the ends of" the partitions joinedtogether,if so desired. Secured to all but one of the partitions D, andon both sides thereof, are one or more sub-partitions D", formingsub-chambers E', as shown in Figs. 2 and 5. The walls of the saidpartitions D" and D are vertically perforated, so as to form a series ofopenings, a, therein, those in the partitions D" being at the oppositeend of the subchambers E' from that of the openings inV the partition D,as shown in the said Figs. 2 and 5, whereby an increased length oftravel Within a small compass is given to the gas while mixing with theair. In the upper por tion of the tank B is formed apurifying-chamber,F, having an opening, b, communicating with one of the chambers E.

B represents an inlet-pipe leading into one of the chambers E, andextending therein to near the bottoni thereof, as shown in Fig. l.

B" represents a short outlet-pipe leading from the top of one of saidchambers E.

Thelid or cover of tankB is preferably raised in the center, and hasopenings G leading, respectively, into e'ach of said chambers E, saidopenings being provided with screw'caps G' to close the same.

H represents a trough or basin on the upper side of the lid of the tankB, and so placed as to form a seal for said openings G.' A c`ap,J, isinserted within the trough H, covering the screw-caps G', and a lid,K,covers the trough, being secured in place by means of a lock, L, whichconsists of a bar, L', having a recessed portion on one side at thecenter thereof, and a ange portion, L", at the other end with an openingtherein. To secure said bar, one end thereof is iirst inserted into anotched arm of the standard M, and the recessed central portion isbrought in contact with the dischargepipe R, and the flange/portion ofthe bar suitably secured to the standard M', the lock-nut T beingbrought against the upper face ofthe bar.

N represent an. inlet-pipe leading into one of the chambers E, havingattached thereto a iieXible tube, O, having a iioat, P. so secured toits lower end that the horizontal exit of ma` terial therefrom is atorabont the level of the hydrocarbon in the chamber, so that the in-'flowing material-will mix more nreadily with the said hydrocarbon.Y

R represents an outlet-pipe leading from the chamber F of the tank B.Between the pipes N and R is a by-pipe, S, and the said pipes N, R, andS have suitable cocks, c, d, and e, respectively.

All thc chambers E, except the one in which the tubing O and the iioat Pare placed, are partially filled with sponge suspended froina frame orin any other way, so as to keep the same from touching the Hoor of thechamber, and being compressed during the process of gas-generation. Abar is shown in the dra-wings, Fig. l, as a means of accomplishing thisresult, but wire-cloth or other means may be used, and applicant doesnot therefore limit himself to the employment of a bar. This sponge isinserted or placed within the said chambers through the openings G,which readily permit the withdrawal of the same when IOO needed withoutkthe tank B being taken to pieces. .The purifying-chamber F is suitablypacked or filled with the oxide of iron or other suitable purifyingmaterial.

The manner of operating the device is as follows: The chambers E of theinner tank, B, are filled with gasoline or other suitable hydrocarbonnearly to the top of the vertical line of openings a by means of theinlet-pipe B', after which the said pipe B', as well as all the openingsG, are securely closed,and either street-gas or air introduced by thepipe N into the first of the chambers E. The gas generated within thetank will be forced through the openings c into and through the chambersE and E', and into the purifying-chambers F, owing to the pressure ofthe street-gas or air, which will mix with the generated gas during itstravel through the said chambers. The inletpipe B' is also used forremoving the residue from the inner tank.

I am aware that it is not new to form carburetors with several chamberstherein communicating with each other; neither is it new to constructthe saine with strips placed alongside of plates which form partitionsand to have zigzag folded surfaces extending over projecting edges,whereby a communication is maintained between the respective chambers;

neither is it new to employ a iioat in connection with a jointed gas orair-inlet pipe for the purpose of admitting the air or gas into the tankabove the hydrocarbon therein, and such I do not broadly claim; but, sofar as I am aware, perforated partitions and sub-partitions similar tothose herein described have not been employed in carburetors; `neitherhas a iiexible pipe so connected with a float as to have a horizontalexit therefrom into the tank been made use of in connection therewith.By the construction of the perforated partitions and sub-partitions, asdescribed, I am able to obtain a much longer length of travel of thefluids while mixing, and thereby a much better production, while thehorizontal exit of the air or gas upon the surface of the hydrocarbonalso assists in the more readily mixing of the materials. 'Ihesepeculiarities of construction are of importance in the production of thegas, aiding in making a better article and that in a shorter time.

What I claim, and desire to secure by Let ters Patent of the UnitedStates, is.-

I. A carburetor provided with an oil-supply pipe, inlet and outletpipes, and having an inner tank with vertical partitions formingchambers and subpartitions secured at their ends to the partitionsforming subchambers, the said partitions and sub-partitions havingvertical perforations, whereby said chambers and sub-chambers form acontinuous passage within the tank, all substantially as described.

2. A jacketed carburetor provided with an oil-supply pipe and inlet andoutletpipes, and having an inner tank, B, with vertical partitions D andvertical sub-partitions D" joined to said partitions D, said partitionsD and subpartitions D" forming a series of communicat ing chambers, E,and sub-chambers E', and each having vertical perforations a, soarranged as to form of said chambers and sub-chambers acontinuouspassage, all substantially as described.

3. In a jacketed carburetor, an inner tank having perforated partitions,as described, forming communicating vertical chambers E, and a coverhaving openin gs AGr and caps G', all of said parts combinedsubstantially as described.
